Writing Research Papers

• What Types of References Are Appropriate?

When writing a research paper, there are many different types of sources that you might consider citing.  Which are appropriate?  Which are less appropriate?  Here we discuss the different types of sources that you may wish to use when working on a research paper.   

Please note that the following represents a general set of recommended guidelines that is not specific to any class and does not represent department policy.  The types of allowable sources may vary by course and instructor.

Highly appropriate: peer-reviewed journal articles

In general, you should primarily cite peer-reviewed journal articles in your research papers.  Peer-reviewed journal articles are research papers that have been accepted for publication after having undergone a rigorous editorial review process.  During that review process, the article was carefully evaluated by at least one journal editor and a group of reviewers (usually scientists that are experts in the field or topic under investigation).  Often the article underwent revisions before it was judged to be satisfactory for publication. 

Most articles submitted to high quality journals are not accepted for publication.  As such, research that is successfully published in a respected peer-reviewed journal is generally regarded as higher quality than research that is not published or is published elsewhere, such as in a book, magazine, or on a website.  However, just because a study was published in a peer-reviewed journal does not mean that it is free from error or that its conclusions are correct.  Accordingly, it is important to critically read and carefully evaluate all sources, including peer-reviewed journal articles.

Tips for finding and using peer-reviewed journal articles:

• Many databases, such as PsycINFO, can be set to only search for peer-reviewed journal articles. Other search engines, such as Google Scholar, typically include both peer-reviewed and not peer-reviewed articles in search results, and thus should be used with greater caution. 
• Even though a peer-reviewed journal article is, by definition, a source that has been carefully vetted through an editorial process, it should still be critically evaluated by the reader. 

Potentially appropriate: books, encyclopedias, and other scholarly works

Another potential source that you might use when writing a research paper is a book, encyclopedia, or an official online source (such as demographic data drawn from a government website).  When relying on such sources, it is important to carefully consider its accuracy and trustworthiness.  For example, books vary in quality; most have not undergone any form of review process other than basic copyediting.  In many cases, a book’s content is little more than the author’s informed or uninformed opinion. 

However, there are books that have been edited prior to publication, as is the case with many reputable encyclopedias; also, many books from academic publishers are comprised of multiple chapters, each written by one or more researchers, with the entire volume carefully reviewed by one or more editors.  In those cases, the book has undergone a form of peer review, albeit often not as rigorous as that for a peer-reviewed journal article.

Tips for using books, encyclopedias, and other scholarly works:

• When using books, encyclopedias, and other scholarly works (that is, works written or produced by researchers, official agencies, or corporations), it is important to very carefully evaluate the quality of that source.
• If the source is an edited volume (in which case in the editor(s) will be listed on the cover), is published by a reputable source (such as Academic Press, MIT Press, and others), or is written by a major expert in the field (such as a researcher with a track record of peer-reviewed journal articles on the subject), then it is more likely to be trustworthy.
• For online encyclopedias such as Wikipedia, an instructor may or may not consider that an acceptable source (by default, don’t assume that a non-peer reviewed source will be considered acceptable). It is best to ask the instructor for clarification. 1

Usually inappropriate: magazines, blogs, and websites  

Most research papers can be written using only peer-reviewed journal articles as sources.  However, for many topics it is possible to find a plethora of sources that have not been peer-reviewed but also discuss the topic.  These may include articles in popular magazines or postings in blogs, forums, and other websites.  In general, although these sources may be well-written and easy to understand, their scientific value is often not as high as that of peer-reviewed articles.  Exceptions include some magazine and newspaper articles that might be cited in a research paper to make a point about public awareness of a given topic, to illustrate beliefs and attitudes about a given topic among journalists, or to refer to a news event that is relevant to a given topic. 

Tips for using magazines, blogs, and websites:

• Avoid such references if possible. You should primarily focus on peer-reviewed journal articles as sources for your research paper.  High quality research papers typically do not rely on non-academic and not peer-reviewed sources.
• Refer to non-academic, not peer-reviewed sources sparingly, and if you do, be sure to carefully evaluate the accuracy and scientific merit of the source.

13.2 Citing and Referencing Techniques

Learning objective.

• Apply American Psychological Association (APA) style formatting guidelines for citations.

This section covers the nitty-gritty details of in-text citations. You will learn how to format citations for different types of source materials, whether you are citing brief quotations, paraphrasing ideas, or quoting longer passages. You will also learn techniques you can use to introduce quoted and paraphrased material effectively. Keep this section handy as a reference to consult while writing the body of your paper.

Formatting Cited Material: The Basics

As noted in previous sections of this book, in-text citations usually provide the name of the author(s) and the year the source was published. For direct quotations, the page number must also be included. Use past-tense verbs when introducing a quote—“Smith found…” and not “Smith finds.…”

Formatting Brief Quotations

For brief quotations—fewer than forty words—use quotation marks to indicate where the quoted material begins and ends, and cite the name of the author(s), the year of publication, and the page number where the quotation appears in your source. Remember to include commas to separate elements within the parenthetical citation. Also, avoid redundancy. If you name the author(s) in your sentence, do not repeat the name(s) in your parenthetical citation. Review following the examples of different ways to cite direct quotations.

Chang (2008) emphasized that “engaging in weight-bearing exercise consistently is one of the single best things women can do to maintain good health” (p. 49).

The author’s name can be included in the body of the sentence or in the parenthetical citation. Note that when a parenthetical citation appears at the end of the sentence, it comes after the closing quotation marks and before the period. The elements within parentheses are separated by commas.

Weight Training for Women (Chang, 2008) claimed that “engaging in weight-bearing exercise consistently is one of the single best things women can do to maintain good health” (p. 49).

Weight Training for Women claimed that “engaging in weight-bearing exercise consistently is one of the single best things women can do to maintain good health” (Chang, 2008, p. 49).

Including the title of a source is optional.

In Chang’s 2008 text Weight Training for Women , she asserts, “Engaging in weight-bearing exercise is one of the single best things women can do to maintain good health” (p. 49).

The author’s name, the date, and the title may appear in the body of the text. Include the page number in the parenthetical citation. Also, notice the use of the verb asserts to introduce the direct quotation.

“Engaging in weight-bearing exercise,” Chang asserts, “is one of the single best things women can do to maintain good health” (2008, p. 49).

You may begin a sentence with the direct quotation and add the author’s name and a strong verb before continuing the quotation.

Formatting Paraphrased and Summarized Material

When you paraphrase or summarize ideas from a source, you follow the same guidelines previously provided, except that you are not required to provide the page number where the ideas are located. If you are summing up the main findings of a research article, simply providing the author’s name and publication year may suffice, but if you are paraphrasing a more specific idea, consider including the page number.

Read the following examples.

Chang (2008) pointed out that weight-bearing exercise has many potential benefits for women.

Here, the writer is summarizing a major idea that recurs throughout the source material. No page reference is needed.

Chang (2008) found that weight-bearing exercise could help women maintain or even increase bone density through middle age and beyond, reducing the likelihood that they will develop osteoporosis in later life (p. 86).

Although the writer is not directly quoting the source, this passage paraphrases a specific detail, so the writer chose to include the page number where the information is located.

Although APA style guidelines do not require writers to provide page numbers for material that is not directly quoted, your instructor may wish you to do so when possible.

Check with your instructor about his or her preferences.

Formatting Longer Quotations

When you quote a longer passage from a source—forty words or more—use a different format to set off the quoted material. Instead of using quotation marks, create a block quotation by starting the quotation on a new line and indented five spaces from the margin. Note that in this case, the parenthetical citation comes after the period that ends the sentence. Here is an example:

In recent years, many writers within the fitness industry have emphasized the ways in which women can benefit from weight-bearing exercise, such as weightlifting, karate, dancing, stair climbing, hiking, and jogging. Chang (2008) found that engaging in weight-bearing exercise regularly significantly reduces women’s risk of developing osteoporosis. Additionally, these exercises help women maintain muscle mass and overall strength, and many common forms of weight-bearing exercise, such as brisk walking or stair climbing, also provide noticeable cardiovascular benefits. (p. 93)

Review the places in your paper where you cited, quoted, and paraphrased material from a source with a single author. Edit your citations to ensure that

• each citation includes the author’s name, the date of publication, and, where appropriate, a page reference;
• parenthetical citations are correctly formatted;
• longer quotations use the block-quotation format.

If you are quoting a passage that continues into a second paragraph, indent five spaces again in the first line of the second paragraph. Here is an example:

In recent years, many writers within the fitness industry have emphasized the ways in which women can benefit from weight-bearing exercise, such as weightlifting, karate, dancing, stair climbing, hiking, and jogging. Chang (2008) found that engaging in weight-bearing exercise regularly significantly reduces women’s risk of developing osteoporosis. Additionally, these exercises help women maintain muscle mass and overall strength, and many common forms of weight-bearing exercise, such as brisk walking or stair climbing, also provide noticeable cardiovascular benefits.

It is important to note that swimming cannot be considered a weight-bearing exercise, since the water supports and cushions the swimmer. That doesn’t mean swimming isn’t great exercise, but it should be considered one part of an integrated fitness program. (p. 93)

Be wary of quoting from sources at length. Remember, your ideas should drive the paper, and quotations should be used to support and enhance your points. Make sure any lengthy quotations that you include serve a clear purpose. Generally, no more than 10–15 percent of a paper should consist of quoted material.

Introducing Cited Material Effectively

Including an introductory phrase in your text, such as “Jackson wrote” or “Copeland found,” often helps you integrate source material smoothly. This citation technique also helps convey that you are actively engaged with your source material. Unfortunately, during the process of writing your research paper, it is easy to fall into a rut and use the same few dull verbs repeatedly, such as “Jones said,” “Smith stated,” and so on.

Punch up your writing by using strong verbs that help your reader understand how the source material presents ideas. There is a world of difference between an author who “suggests” and one who “claims,” one who “questions” and one who “criticizes.” You do not need to consult your thesaurus every time you cite a source, but do think about which verbs will accurately represent the ideas and make your writing more engaging. The following chart shows some possibilities.

Review the citations in your paper once again. This time, look for places where you introduced source material using a signal phrase in your sentence.

• Highlight the verbs used in your signal phrases, and make note of any that seem to be overused throughout the paper.
• Identify at least three places where a stronger verb could be used.
• Make the edits to your draft.

Writing at Work

It is important to accurately represent a colleague’s ideas or communications in the workplace. When writing professional or academic papers, be mindful of how the words you use to describe someone’s tone or ideas carry certain connotations. Do not say a source argues a particular point unless an argument is, in fact, presented. Use lively language, but avoid language that is emotionally charged. Doing so will ensure you have represented your colleague’s words in an authentic and accurate way.

Formatting In-Text Citations for Other Source Types

These sections discuss the correct format for various types of in-text citations. Read them through quickly to get a sense of what is covered, and then refer to them again as needed.

Print Sources

This section covers books, articles, and other print sources with one or more authors.

A Work by One Author

For a print work with one author, follow the guidelines provided in Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.1 “Formatting a Research Paper” . Always include the author’s name and year of publication. Include a page reference whenever you quote a source directly. (See also the guidelines presented earlier in this chapter about when to include a page reference for paraphrased material.)

Two or More Works by the Same Author

At times, your research may include multiple works by the same author. If the works were published in different years, a standard in-text citation will serve to distinguish them. If you are citing multiple works by the same author published in the same year, include a lowercase letter immediately after the year. Rank the sources in the order they appear in your references section. The source listed first includes an a after the year, the source listed second includes a b , and so on.

Rodriguez (2009a) criticized the nutrition-supplement industry for making unsubstantiated and sometimes misleading claims about the benefits of taking supplements. Additionally, he warned that consumers frequently do not realize the potential harmful effects of some popular supplements (Rodriguez, 2009b).

If you have not yet created your references section, you may not be sure which source will appear first. See Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.3 “Creating a References Section” for guidelines—or assign each source a temporary code and highlight the in-text citations so you remember to double-check them later on.

Works by Authors with the Same Last Name

If you are citing works by different authors with the same last name, include each author’s initials in your citation, whether you mention them in the text or in parentheses. Do so even if the publication years are different.

J. S. Williams (2007) believes nutritional supplements can be a useful part of some diet and fitness regimens. C. D. Williams (2008), however, believes these supplements are overrated.

According to two leading researchers, the rate of childhood obesity exceeds the rate of adult obesity (K. Connelley, 2010; O. Connelley, 2010).

Studies from both A. Wright (2007) and C. A. Wright (2008) confirm the benefits of diet and exercise on weight loss.

A Work by Two Authors

When two authors are listed for a given work, include both authors’ names each time you cite the work. If you are citing their names in parentheses, use an ampersand (&) between them. (Use the word and , however, if the names appear in your sentence.)

As Garrison and Gould (2010) pointed out, “It is never too late to quit smoking. The health risks associated with this habit begin to decrease soon after a smoker quits” (p. 101).

As doctors continue to point out, “It is never too late to quit smoking. The health risks associated with this habit begin to decrease soon after a smoker quits” (Garrison & Gould, 2010, p. 101).

A Work by Three to Five Authors

If the work you are citing has three to five authors, list all the authors’ names the first time you cite the source. In subsequent citations, use the first author’s name followed by the abbreviation et al. ( Et al. is short for et alia , the Latin phrase for “and others.”)

Henderson, Davidian, and Degler (2010) surveyed 350 smokers aged 18 to 30.

One survey, conducted among 350 smokers aged 18 to 30, included a detailed questionnaire about participants’ motivations for smoking (Henderson, Davidian, & Degler, 2010).

Note that these examples follow the same ampersand conventions as sources with two authors. Again, use the ampersand only when listing authors’ names in parentheses.

As Henderson et al. (2010) found, some young people, particularly young women, use smoking as a means of appetite suppression.

Disturbingly, some young women use smoking as a means of appetite suppression (Henderson et al., 2010).

Note how the phrase et al. is punctuated. No period comes after et , but al. gets a period because it is an abbreviation for a longer Latin word. In parenthetical references, include a comma after et al. but not before. Remember this rule by mentally translating the citation to English: “Henderson and others, 2010.”

A Work by Six or More Authors

If the work you are citing has six or more authors, list only the first author’s name, followed by et al. , in your in-text citations. The other authors’ names will be listed in your references section.

Researchers have found that outreach work with young people has helped reduce tobacco use in some communities (Costello et al., 2007).

A Work Authored by an Organization

When citing a work that has no individual author(s) but is published by an organization, use the organization’s name in place of the author’s name. Lengthy organization names with well-known abbreviations can be abbreviated. In your first citation, use the full name, followed by the abbreviation in square brackets. Subsequent citations may use the abbreviation only.

It is possible for a patient to have a small stroke without even realizing it (American Heart Association [AHA], 2010).

Another cause for concern is that even if patients realize that they have had a stroke and need medical attention, they may not know which nearby facilities are best equipped to treat them (AHA, 2010).

• Review the places in your paper where you cited material from a source with multiple authors or with an organization as the author. Edit your citations to ensure that each citation follows APA guidelines for the inclusion of the authors’ names, the use of ampersands and et al. , the date of publication, and, where appropriate, a page reference.
• Mark any additional citations within your paper that you are not sure how to format based on the guidelines provided so far. You will revisit these citations after reading the next few sections.

A Work with No Listed Author

If no author is listed and the source cannot be attributed to an organization, use the title in place of the author’s name. You may use the full title in your sentence or use the first few words—enough to convey the key ideas—in a parenthetical reference. Follow standard conventions for using italics or quotations marks with titles:

• Use italics for titles of books or reports.
• Use quotation marks for titles of articles or chapters.

“Living With Diabetes: Managing Your Health” (2009) recommends regular exercise for patients with diabetes.

Regular exercise can benefit patients with diabetes (“Living with Diabetes,” 2009).

Rosenhan (1973) had mentally healthy study participants claim to be experiencing hallucinations so they would be admitted to psychiatric hospitals.

A Work Cited within Another Work

To cite a source that is referred to within another secondary source, name the first source in your sentence. Then, in parentheses, use the phrase as cited in and the name of the second source author.

Rosenhan’s study “On Being Sane in Insane Places” (as cited in Spitzer, 1975) found that psychiatrists diagnosed schizophrenia in people who claimed to be experiencing hallucinations and sought treatment—even though these patients were, in fact, imposters.

Two or More Works Cited in One Reference

At times, you may provide more than one citation in a parenthetical reference, such as when you are discussing related works or studies with similar results. List the citations in the same order they appear in your references section, and separate the citations with a semicolon.

Some researchers have found serious flaws in the way Rosenhan’s study was conducted (Dawes, 2001; Spitzer, 1975).

Both of these researchers authored works that support the point being made in this sentence, so it makes sense to include both in the same citation.

A Famous Text Published in Multiple Editions

In some cases, you may need to cite an extremely well-known work that has been repeatedly republished or translated. Many works of literature and sacred texts, as well as some classic nonfiction texts, fall into this category. For these works, the original date of publication may be unavailable. If so, include the year of publication or translation for your edition. Refer to specific parts or chapters if you need to cite a specific section. Discuss with your instructor whether he or she would like you to cite page numbers in this particular instance.

In New Introductory Lectures on Psycho-Analysis , Freud explains that the “manifest content” of a dream—what literally takes place—is separate from its “latent content,” or hidden meaning (trans. 1965, lecture XXIX).

Here, the student is citing a classic work of psychology, originally written in German and later translated to English. Since the book is a collection of Freud’s lectures, the student cites the lecture number rather than a page number.

An Introduction, Foreword, Preface, or Afterword

To cite an introduction, foreword, preface, or afterword, cite the author of the material and the year, following the same format used for other print materials.

Electronic Sources

Whenever possible, cite electronic sources as you would print sources, using the author, the date, and where appropriate, a page number. For some types of electronic sources—for instance, many online articles—this information is easily available. Other times, however, you will need to vary the format to reflect the differences in online media.

Online Sources without Page Numbers

If an online source has no page numbers but you want to refer to a specific portion of the source, try to locate other information you can use to direct your reader to the information cited. Some websites number paragraphs within published articles; if so, include the paragraph number in your citation. Precede the paragraph number with the abbreviation for the word paragraph and the number of the paragraph (e.g., para. 4).

As researchers have explained, “Incorporating fresh fruits and vegetables into one’s diet can be a challenge for residents of areas where there are few or no easily accessible supermarkets” (Smith & Jones, 2006, para. 4).

Even if a source does not have numbered paragraphs, it is likely to have headings that organize the content. In your citation, name the section where your cited information appears, followed by a paragraph number.

The American Lung Association (2010) noted, “After smoking, radon exposure is the second most common cause of lung cancer” (What Causes Lung Cancer? section, para. 2).

This student cited the appropriate section heading within the website and then counted to find the specific paragraph where the cited information was located.

If an online source has no listed author and no date, use the source title and the abbreviation n.d. in your parenthetical reference.

It has been suggested that electromagnetic radiation from cellular telephones may pose a risk for developing certain cancers (“Cell Phones and Cancer,” n.d.).

Personal Communication

For personal communications, such as interviews, letters, and e-mails, cite the name of the person involved, clarify that the material is from a personal communication, and provide the specific date the communication took place. Note that while in-text citations correspond to entries in the references section, personal communications are an exception to this rule. They are cited only in the body text of your paper.

J. H. Yardley, M.D., believes that available information on the relationship between cell phone use and cancer is inconclusive (personal communication, May 1, 2009).

At work, you may sometimes share information resources with your colleagues by photocopying an interesting article or forwarding the URL of a useful website. Your goal in these situations and in formal research citations is the same. The goal is to provide enough information to help your professional peers locate and follow up on potentially useful information. Provide as much specific information as possible to achieve that goal, and consult with your professor as to what specific style he or she may prefer.

Revisit the problem citations you identified in Note 13.55 “Exercise 3” —for instance, sources with no listed author or other oddities. Review the guidelines provided in this section and edit your citations for these kinds of sources according to APA guidelines.

Key Takeaways

• In APA papers, in-text citations include the name of the author(s) and the year of publication whenever possible.
• Page numbers are always included when citing quotations. It is optional to include page numbers when citing paraphrased material; however, this should be done when citing a specific portion of a work.
• When citing online sources, provide the same information used for print sources if it is available.
• When a source does not provide information that usually appears in a citation, in-text citations should provide readers with alternative information that would help them locate the source material. This may include the title of the source, section headings and paragraph numbers for websites, and so forth.
• When writing a paper, discuss with your professor what particular standards he or she would like you to follow.

Why Cite Resources?

Citing sources in the body of a research paper tells the reader that outside source material was used in the sentence where the in-text citation appears.  This lets the reader know it is not their original work or thought. Citing sources:

• Lets the reader know whose research or ideas or theories influenced the paper's author
• Provides authority and support for the positions taken in the paper
• Acknowledges others in the field by giving credit for their original work

In-text citations also serve as finding tools. Because in-text citations are composed of the first two elements of the reference for the resource (author's last name and publication date), it provides the reader with enough information to find the resource in the paper’s References list. In other words, in-text citations and references match!

What Needs to be Cited?

According to the Publication Manual of the American Psychological Association (7th ed.),

" Plagiarism is the act of presenting the words, ideas, or images of another as one's own; it denies authors credit where credit is due" (American Psychological Association, 2020, p. 21).

In other words, using information from source material must be cited in the text and in the Reference list of APA-style papers.  This includes using others:

• Words  - Quotations
• Ideas  - Summaries, Paraphrases
• Data  - Numbers, Data
• Images   - Pictures, Charts, Graphs

View examples of references and companion in-text citations in the References page s in the APA Guide.

Creating In-Text Citations: Paraphrases and Summaries

(Author, Date)       

APA style uses the Author-Date citation system. In-text citations appear in the text of the paper to let readers know that information in the sentence where the in-text citation appears was taken from source material. They are composed of the first two elements of the corresponding reference (Author, Date)  for the resource and are designed to be short to avoid disrupting the flow of the paper.

There are two types of in-text citation:

• Parenthetical

Parenthetical In-Text Citation

This is the most common form of in-text citation.  It is composed of the author(s) last name and the year of publication. It is called a parenthetical citation because this information is enclosed in parentheses. The parenthetical citation appears at the end of the sentence where information from the source was used and, because it is a part of the sentence, appears before the period. See the example of a parenthetical citation below:

Students reported they prefer writing on a computer rather than with paper and pen  (Cheung, 2016) .

Narrative In-Text Citation

The narrative citation is used when the author's name is used in a sentence. In this case, the year of publication enclosed in parentheses follows the author's name in the sentence. See the example of a narrative citation below:

In his survey, Cheung  (2016)  found that undergraduate writers produced higher quality writing when composing on a computer rather than with paper and pen.

In-Text Citations and References are Connected and Match!

In-text citations have two functions. First, they alert the reader that information from source material was used in a sentence where the in-text citation appears. It lets the reader know who's work influenced the writer's position or conclusions on the topic. Second, it serves as a finding tool so that the reader can quickly find the full reference in the reference list. The reference and in-text citation need to match. The example below illustrates how these match:

In-text citations follow the Author-Date pattern. In-text citations can appear at the end of a sentence (parenthetical in-text citation) or in the text of the sentence if the author's name is incorporated (narrative in-text citation). If a work is by three or more authors, list the first author's last name followed by the phrase "et al." and the year of publication.

Examples of in-text citations for works by one author, two authors, three or more authors, and group authors appear below:

Work by One Author

    Parenthetical in-text citation              (Davis, 2019).

    Narrative in-text citation                     According to Davis (2019),...

Work by Two Authors

Placing In-Text Citations

In-text citations follow the Author-Date pattern and appear in the sentence where information from source material is used.  Placement of in-text citations vary depending on whether the author(s) name is incorporated into the sentence (narrative citation) or if the author(s) is not named directly in the sentence (parenthetical citation). In-text citations are a part of the sentence and appear before the ending period.

Parenthetical Citations

A parenthetical citation appears when information from source material is used, but the author(s) name is not included in the sentence text. This type of in-text citation is composed of the author(s) last name comma year of publication enclosed in parentheses. It is placed at the end of the sentence before the ending period.  

Narrative Citations

A narrative citation is used when the author(s) name is included in the sentence text. In this case, the year of publication is enclosed in parentheses and appears after the author(s) name.

In his survey,  Cheung  (2016)   found that undergraduate writers produced higher quality writing when composing on a computer rather than with paper and pen.

Creating In-Text Citations: Quotations

Author-Date-#   pattern:

When you copy a portion of the text directly from a source, it is called a  direct quotation . You will enclose the quote in quotation marks, and your citation will contain the last name of the author(s), the year of publication, and page number of where the quote can be found in the source:

If you are using a source that has  pages , then you will use an abbreviated p.:

(Smith, 2018, p. 4).

If you are using a source that does not have pages (a website), then you will use a  paragraph number . You will count down to the paragraph where your quote is located. You will use an abbreviated para.: 

(Wilson & Miller, 2019, para. 2).

Parenthetical In-Text Citation:

If the author’s name is not incorporated in your sentence include the author’s last name, year of publication, and page or paragraph number separated with commas and enclosed in parentheses at the end of the quotation: 

Many writers appreciate the “ability to edit instantaneously”  (Smith, 2008, p. 72)  when writing in pencil or on a computer.

If you incorporate the author’s name into your sentence follow the author's name with the year of publication in parentheses and include the location in parentheses directly following the quote:

In his survey,  Miller (2006)  found that some writers like the sound “of graphite turning ideas into reality”  (p. 72)  when writing in pencil. 

Quotations of 40 or More Words Require Block Format

Quotations of 40 or more words included in a paper are presented in block format. The quotation begins on a new line and the whole quotation is indented 1/2 inch from the left margin. No quotation marks are used and the citation appears at the end of the quotation after the final punctuation mark. In fact, this is the only situation where a parenthetical reference appears outside of a period!

Writing Tip:    Block quotations should be used sparingly.   Remember that your voice is important -- after all it is your paper! Instead of using a block quotation, consider taking pieces of the larger quote and either paraphrase them (put their ideas into your own words and provide an in-text citation) or include precise, shorter quotations from the larger quote, integrated into your own sentences. Either approach will help to ensure that you (the writer) have engaged with information in the quote and directly applied it to the topic of the paper.

Here is an example of a block quotation. Note: Normally the passage would be double spaced but, due to space restrictions, this example is single spaced.

Place direct quotations longer than 40 words in a free-standing block of typewritten lines, and omit quotation marks.  Start the quotation on a new line, indented 1/2 inch from the left margin, i.e., in the same place you would begin a new paragraph.  Type the entire quotation on the new margin, and indent the first line of any subsequent paragraph within the quotation 1/2 inch from the new margin.  Maintain double-spacing throughout.  The parenthetical reference should come after the closing punctuation mark. (Angeli, et al., 2018, para. 27)

To create a block quotation, use the block indent button:

Although paraphrasing information is preferable, there are specific situations when a quotation can be an effective choice.  For example:

• Including a famous or familiar quotation can be effective when introducing a topic or in setting the tone of a paper.
• Providing the words of an expert can bolster your position or argument.
• In rare instances, it may be difficult to paraphrase a short passage without changing the meaning; including a precise quotation may be preferable.
• Sources of facts and statistics--including those presented in tables or charts -- must be documented in your paper using in-text citations and references.
• Including a quotation that opposes your position can be an effective method to prove why your position on the issue is preferable.

Paraphrases and Summaries

Author-Date  pattern:

When you  summarize ,  paraphrase , or otherwise refer to an idea, concept, or fact gained through your research, your citation will contain the last name of the author(s) and the year of publication:

(Smith, 2018)

(Wilson & Miller, 2019)

Qualities of a "Good" Paraphrase

Academic writing often requires students to integrate information found in source material.  There are various ways to do this; quotations, summaries, or paraphrases.  A  paraphrase  is a detailed restatement in your own words of main ideas from the portion of the source that is paraphrased.

Creating a well-written paraphrase can be a challenging skill to learn.  Understanding the qualities of a "good" paraphrase can help. A well-written paraphrase includes the following qualities:

• All of the main details in the original appear in the paraphrase
• The paraphrase does not change the original author's meaning.
• ​The paraphrase is roughly the same length or shorter than the original. 
• ​ The paraphrase is written using language, tone, and style that is your own.
• ​ Paraphrased material must include both an in-text citation and a reference in the References list.

Example of a well-written paraphrase:

Original Passage:

University of Tulsa psychologist Judy Berry studied seventy-three Oklahoma eighth graders who had taken a parenting course.  For ten days, each student had to care for a ten-pound sack of flour as if it were a baby.  Berry's research on her young subjects suggests the course worked.  The teenagers in the study had a sounder sense of parental responsibility than they did before they took the course.

Harper, K. S. (1996). 'Flour babies' surrogacy teaches eight-graders parenting skills.  Journal of Child and Family Studies, 25 (4), 25-28.

Example of a Good Paraphrase:

Extended parental role-playing can actually increase an adolescent's awareness of parental responsibilities as shown by psychologist Judy Berry's study involving eighth grade students (Harper, 1996).

Avoid Patch Writing!

Students learning how to paraphrase may inadvertently "patch write."  Patch writing occurs when a writer uses a passage from source material and changes a few words and phrases before including the passage in a paper or assignment.  Not only is this  "bad" paraphrasing but it is also a form of plagiarism.  View the example below to gain a better understanding of patch writing:

University of Tulsa psychologist Judy Berry studied seventy-three Oklahoma eighth graders who had taken a parenting course.  For ten days, each student had to care for a ten-pound sack of flour as if it were a baby.  Berry's research on her young subjects suggests the course worked.  The teenagers in the study had a sounder sense of parental responsibility than they did before they took the course.

Patchwriting Example:

University of Tulsa psychologist Judy Berry  studied  eighth graders who had taken a parenting course.  Students had to treat  a ten-pound sack of flour as if it were a baby.   The results of Berry's study suggested  that teenagers in the study had a  better understanding  of parental responsibility than they did before they took the course  (Harper, 1996).

TIP:   Notice how the bolded phrases are identical to the original.  Even though there is an in-text citation, patchwriting is still a form of plagiarism.
